Lima Tango CCS

The Lima Tango CCS 1 project is a dedicated carbon dioxide injection and geologic storage project developed by BKV dCarbon Ventures, LLC at the Las Tiendas natural gas processing facility operated by Energy Transfer in McMullen County, Texas. The project involves injection of captured CO₂ into the Middle Eocene Queen City Formation at depths ranging from approximately 3,500 to 4,870 feet, with the storage interval consisting of laterally continuous porous sandstones bounded by thick regional confining shales including the Weches and Reklaw formations. The well is permitted as a Class II injection well by the Texas Railroad Commission and is designed as a non-EOR sequestration operation monitored under EPA Subpart RR monitoring, reporting, and verification requirements. Reservoir modeling indicates an annual injection rate of approximately 177,000 tonnes of CO₂ per year over a planned 12-year injection period, with cumulative storage estimated at roughly 2.1 million tonnes and a modeled plume remaining localized near the injection site. Monitoring programs include pressure and temperature measurements, plume modeling, seismic monitoring through regional networks, leakage detection protocols, and groundwater protection measures to verify containment and long-term storage integrity
